run. >> the fact that he's been taken into custody, that does not negate the fact that there are people out there who are still targeting police officers. >> reporter: david, the person who installed the unique rims on mckane's car recognized them. he will appear in court december 22nd and face capital murder charges. david? >> kayna, thank you. next tonight, president-elect donald trump, and to what appears to be a major change of heart on hillary clinton. after countless rallies where he stood before supporters chanting "lock her up," tonight, he is now indicating, he is not inclined to pursue further investigation of clinton, saying he doesn't want to hurt the clintons. he was also asked by "the new york times" about those nazi salutes. the group seen celebrating his win. mr. trump saying if they're energized, he wanted to know why. abc's david wright at trump tower tonight. >> reporter: today, donald trump at "the new york times," on the record, backing away from one of his harshest campaign promises. >> lock her up! lock her up!

lock her up! >> reporter: the threat to pursue criminal charges against his opponent, hillary clinton. >> if i win, i am going to instruct my attorney general to get a special prosecutor to look into your situation, because there has never been so many lies, so much deception. >> reporter: today, trump acknowledged he's having second thoughts. "my inclination would be for whatever power i have on the matter is to say, let geese forward. this has been looked at for so long,ed a nauseam." he didn't entirely rule out prosecuting clinton, but said, "i think it would be very, very divisive for the country." earlier today, trump's senior adviser said, trump is now the head of the republican paratishgs and she hopes other republicans follow his lead. >> if donald trump can help her heal, perhaps that's a good thing. he's thinking of many different things as he prepares to become the president of the united states, and things that sound like the campaign aren't among them.

>> reporter: clinton was spotted this weekend at a bookstore in rhode island. the woman who posted this picture to her facebook said, "i told her i voted for her, that she meant and means a lot. i thanked her, apologizing if i was being inappropriate, a" adding, "she was gracious, warm." today at "the times," trump insisted, "i don't want to hurt the clintons, i really don't. she went through a lot and suffered greatly." in his interview with "the times," the president-elect said he condemns this group, white nationalists meeting in washington who cheered his victory with nazi salutes and cries of "hail trump." it "it's not a group i want to energy," trump told the paper. "and if they are, i want to find out why." the man in the video is richard spencer, widely credited with creating the term alt-right. trump's chief strategist, steve bannon, has come under fire here

his own association with the alt-right. today, the president-elect defended him, saying, "if i thought he was a racist of alt-right, i wouldn't think about hiring him." bannon will have a top rule at the white house trump said he will rely on jared kushner on advice, saying he could help broker peace between israel and the palestinians. >> and david wright, mr. trump was asked about torture today by "the new york times," and we had asked him about it, and he told me, "i would bring back waterboarding and i would bring back a lot worse." today, we heard something very different. >> reporter: something very different, david. trump says he's changed his mind about waterboarding, after sitting down with general james mat tis, retired general who is a candidate for secretary of defense. trump said that mat tis told him that building trust is a lot more effective than torture, so trump now says, "torture is not going to make the kind of difference that a lot of people are thinking." david? >> david wright tonight, thank

you. mr. trump was also asked about his business, and potential conflicts of interest. the president-elect once saying in the campaign, if elected, "i couldn't care less about my company, it's peanuts." here's abc's chief investigative correspondent, brian ross. >> reporter: with growing concerns tonight, donald trump told "the new york times," "the law is on my side. the president can't have a conflict of interest." but throughout the campaign, trump had pledged to leave his business empire behind. >> if i become president, i couldn't care less about my company. >> reporter: yet, in the two weeks since the election, trump has taken the time to meet with the indian developers of two trump towers in their country, who posted this picture and then took it down. he complained to a british politician about eye sore wind turbines near his scottish golf course. his daughter ivanka's jewelry company tried to cash in on her appearance on "60 minutes" to sell her line of $10,000

bracelets. since then, trump has included his daughter in a meeting with the japanese prime minister, as she prepared to take over his company, which already has been seeking deals in asia. trump defended that today, saying, "if it were up to some people, i would never, ever see my daughter ivanka again." trump has investments or deals in at least 18 countries around the world. now, some of his own advisers fear the president-elect is already creating conflicts. >> you're going to have foreign entities, foreign governments offering sweetheart deals in the hope of favorable action from the president of the united states. >> reporter: and today, there are new quells whether trump, as president, would take actions to help a huge german bank, which has loaned him more than $300 million. trump used the money to buy the dural golf course in florida and build hotels in chicago and his new one in washington. but deutsche bank is also now the target of two major investigations by the u.s. department of justice, facing a possible $14 billion settlement,

which could imperil the bank and effect trump's loans. senator richard blumenthal, a democrat, is calling for a special prosecutor to make sure the justice department does not back down. >> there's a clear conflict of interest between donald trump's personal business interests and his public duties, in fact, his public trust. >> reporter: not for donald trump, who said today, "in theory, i could run my business perfectly and then run the country perfectly," adding, "there's never been a case like this." >> brian ross is with us tonight. and the president-elect said something more to "the new york times," in fact, he said, "the law is totally on my side here." >> there is no low that quires the president to give up his business or put it in a blind trust. trump says he'd like to do something to address ethics issues, but he also seems to be suggesting that he could continue to be involved with his business in some limited way and there's nothing legally to prevent him from doing that, david.

>> the scrutiny that comes when you're elected president. brian, thank you. next, this evening, with millions preparing to mark thanksgiving, the new security warning, just out tonight. the department of homeland security and the fbi now issuing a joint bulletin to local authorities, urging vigilance from now through the holidays, right until the inauguration. it comes as police here in new york city tonight are already going to extreme lengths to protect thousands of people arriving for the thanksgiving day parade. and here's abc's ryan smith. >> reporter: tonight, police in new york stepping up security ahead of thursday's famed thanksgiving day parade. >> i think this year you are going to see a lot more blocker cars and sand trucks on the cross streets. >> reporter: federal authorities issues a clear message to law enforcement agencies across the country. be vigilant this holiday season, through the presidential inauguration in january, as celebrations could be targeted by international terrorists or homegrown violent extremists. just yesterday, police in new york arresting this man, who prosecutors said talked of a times square attack, similar to
